Rumor spreading in interdependent social networks

Social networks have been witnessed tremendous success and become an indispensable part of people's daily life. Thus, many other applications are integrated into social networks to achieve better popularity and efficiency. Unfortunately, novel security problems are emerging as the mutual cooperation and dependence contribute to forming the interdependent networks which are vulnerable for cascading failures. However, when it is come to the social networks involved interdependent networks, one of the most critical security threats is rumor propagation which caused harmful impact such as slander, fraud and panic. In this paper, we examined the security environment for interdependent social networks. The spreader-ignorant-doubter-stifler (SIDR) model is proposed to study the rumor spreading in the interdependent social networks. After theoretical and numerical analysis, the targeted security arrangements are proposed to enhance the security.
